SPECIFICATION forming part of Letters Patent N 0. 665,940, dated January15, 1901.

A fi ti fil d May 19, 1990. $erial No. 17,220. (No model.)

To aZZ whom. it may concern:

Be it known that I, HENRY F. SCHWENKER,

of the city of St. Louis, in the State of Missouri, have inventedcertain new and useful Improvementsin Hinges, of which the following isa full, clear, and exact description, reference being had to theaccompanying drawings, forming aparthereof.

This invention relates to improvements in hinges for cellar-doors; andit consists in the novel arrangement, construction, and com bination ofparts, as will be more fully hereinafter described, and set forth in theclaim.

One object of this invention is to construct a hinge to be used onordinary outside cellardoors and so arranged as to be perfectly solidand rigid when embedded in a concrete foundation.

Another object is by its use the wooden frame of a cellar-door isentirely dispensed with.

Figure 1 is a top plan view of a cellar-door, showing my improved hingein position. Fig.

2 is an enlarged vertical sectional view of a portion of a cellar-doorand concrete foundation, showing my improved hinge in position. Fig. 3is a perspective view of the hinge. Fig. 4 is a perspective view of ahinge made use of for supporting very heavy doors.

In the construction of the device as shown I provide a strap composed offlat wroughtiron of sufficient length and is bent at 1, forming a loop2, its end 3 resting upon the top of the strap. (See Fig. 3.) Said strapis provided with bores 4, through which are passed bolts by which saidstrap is securely held to the door. Through the loop 2 is passed andheld a strip of material 5, each end being bent at right angles, forminga U- shaped rod, which ends are again bent at 6 and again at 7, forminga double right angle, the purpose of which is to allow the supportingend to project near the foundation end.

(See Fig. 2.) The rod is again bent at 8 in a horizontal plane and theends flattened and spread, and each provided with a slit 9, the purposeof which is to allow the concrete to pass therein and cause the same tobe more rigidly supported and fixed. The flared ends and the bentportion of the rod are embedded in the concrete up to the verticalU-shaped portion, allowing just enough of the support ing end to projectto correspond to the thickness of the door and strap to be swung.

The doors upon which this class of hinge is used are sidewalkcellar-doors such as are level with the concrete walk.

In cases where very heavy iron doors are used I construct the hinge asshown in Fig. 4, which is of a very heavy wide strip of iron or likematerial and rounded at the cent-er to provide for the swinging of thestrap.

This device is very simple in construction and is of much saving toproperty on account of dispensing with wooden outside frames whichheretofore was necessary in order to support the hinge.

Having fully described my invention, what I claim is-- A hinge forcellar-doors, constructed of a rod bent U-shaped, said rod again bent at6 and again at 7 forming a double right angle, said rod again bent at 8its ends in a horizontal plane, the ends flattened, split, and spread,said spread ends adapted to be embedded in concrete, a strap carried bysaid rod in the U-shaped portion, and secured to the door for carryingthe same, substantially as specified.

In testimony whereof I affix. my signature in the presence of twowitnesses.

HENRY F. SOHWENKER.
